He-Ne激光辐照铁棍山药贮藏保鲜的研究

Storage of Tiegun dioscorea opposita thunb by He-e laser irradiation

  • 摘要: 用工作波长632.8nm、功率为2.5mW的He-e激光器辐照铁棍山药,30min后,其芦头芽萌发受抑,山药茎含水量、可溶性总糖和可溶性蛋白含量分别从70.2039%下降到66.61544%、从72.21325mgg-1下降到25.87888mgg-1、从508.5394gg-1下降到258.4231gg-1,丙二醛(MDA)和超氧阴离子含量分别从0.62mmolg-1变为8.033122mmolg-1、从32.99713gg-1变为35.53642gg-1,贮藏前期的超氧化物歧化酶(SOD)活性从494.864Ug-1变为1105.85Ug-1,贮藏后期的SOD活性从1105.85Ug-1变为959.167Ug-1。

     

    Abstract: The Lo bud germination inhibition of Tiegun dioscorea opposita thunb occurred, the yam stem water content, total soluble sugar and soluble protein content respectively declined from 70.2039% to 66.61544%, from 72.21325mgg-1 to 25.87888mgg-1 and from 508.5394gg-1 to 258.4231gg-1, and MDA and O2 contents respectively increased from 0.62mmolg-1 to 8.033122mmolg-1 and from 32.99713gg-1 to 35.53642gg-1 after it was irradiated by 2.5mW He-e laser for 30min. After the laser irradiation, the superoxide dismutase (SOD) activity of Tiegun dioscorea opposita thunb increased from 494.864Ug-1 to 1105.85Ug-1 in the initial period of its storage and then declined from 1105.85Ug-1 to 959.167Ug-1.
